wifi: rtw89: fix physts IE page check

2022-11-22T10:16:22Z

The index RTW89_PHYSTS_BITMAP_NUM is not a valid physts IE page. So, fix the check condition.

wifi: rtw89: switch BANDEDGE and TX_SHAPE based on OFDMA trigger frame

2022-11-22T10:15:30Z

There are some registers for transmit waveform control, two of them used in this change are for BANDEDGE and TX_SHAPE control. BANDEDGE controls whether to apply band edge filter to transmit waveform. TX_SHAPE controls whether to apply triangular mask to transmit waveform. It is found for some chip, these two should be turned off during OFDMA UL traffic for better performance.

wifi: rtw89: collect and send RF parameters to firmware for WoWLAN

2022-11-01T09:26:12Z

For WoWLAN mode, we only collect and send RF parameters to Firmware without writing RF registers. So we add one function to practice it. Signed-off-by: Chih-Kang Chang Signed-off-by: Ping-Ke Shih Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20221027052707.14605-2-pkshih@realtek.com

wifi: rtw89: phy: add dummy C2H handler to avoid warning message

2022-10-19T05:57:51Z

The C2H class 2 function 3 is to report retry count of low rate, but driver doesn't implement yet, so add a dummy case to avoid message: rtw89_8852be 0000:03:00.0: c2h class 2 not support Signed-off-by: Ping-Ke Shih Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20221014060237.29050-4-pkshih@realtek.com

wifi: rtw89: 8852b: add chip_ops::set_channel

2022-10-11T16:45:20Z

set_channel is main function to configure channel and bandwidth for all layers, namely MAC, BB and RF. Additionally, MAC layer enables CCK rate checking to avoid wrong rate from driver. BB layer configures SCO (Sample Clock Offset) for CCK, TX gain error/offset, and reset baseband hardware circuit after all configurations done.

wifi: rtw89: 8852b: set proper configuration before loading NCTL

2022-10-11T16:45:19Z

Before loading RF NCTL table, we need to configure IQK/DPK clock and reset them, and then polling NCTL state ready. Since 8852BE needs additional one setting, add it by this patch. Also, give them proper names. Signed-off-by: Ping-Ke Shih Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20221005083212.45683-4-pkshih@realtek.com

wifi: rtw89: phy: ignore warning of bb gain cfg_type 4

2022-10-05T07:42:48Z

The new BB parameters add new cfg_tpe 4 to improve performance of eFEM modules (rfe_type >= 50), but we are using iFEM modules for now, so this warning can be ignored. Signed-off-by: Ping-Ke Shih Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20220930133659.7789-2-pkshih@realtek.com

wifi: rtw89: phy: make generic txpwr setting functions

2022-10-04T07:17:37Z

Previously, we thought control registers or setting things for TX power series may change according to chip. So, setting functions are implemented chip by chip. However, until now, the functions keep the same among chips, at least 8852A, 8852C, and 8852B. There is a sufficient number of chips to share generic setting functions. So, we now remake them including TX power by rate, TX power offset, TX power limit, and TX power limit RU as generic ones in phy.c. Besides, there are some code refinements in the generic ones, but almost all of the logic doesn't change.

wifi: rtw89: send OFDM rate only in P2P mode

2022-09-24T12:36:27Z

Check IEEE80211_TX_CTL_NO_CCK_RATE flag to avoid sending frames with CCK rates in 2GHz band. In TX flow, add IEEE80211_TX_CTL_NO_CCK_RATE flag to check and get its lowest rate without CCK rates if the TX type is mgmt frames or data frames. Besides, the decision of phy rate and retry rate in P2P mode are also be handled. In P2P GO mode, it should send beacon of no CCK rates in its frame rate. Therefore, We add a condition to decide which rate is added to beacon content. Moreover, we avoid setting a mask of rates to be used for rate control selection before and after connection in P2P mode.
